Product/data entry to oscommerce site

I have a project of approx 1000 stock items that need loading into my new oscommerce site. 75% repeat items that only need the colour in the title changing and the photo the other 25% will be items with different descriptions. All description can be found on one of our other websites and images are all sized ready to be uploaded.

General information title, price,decription &amp; image are the only requirements. We would like to start work on this as soon as possible.
